Ahhhh,
thanks that indeed explains what is going on.
My issue now is how do I solve my :with filter for my tags in the best way..
params[:g] ||= []
:with => { tag_ids => params[:g] } does not work when params[:g] is empty
but of course so does
:with_all => { tag_ids => params[:g] } but it is not the way I want it to
work.
Any ideas ?
